合并是星系演化标准范式的基础，并为超大质量黑洞双星提供了一种自然形成机制。这种双星的形成过程可能会直接影响恒星被一个或另一个黑洞潮汐破坏的速度，而潮汐破坏的发光信号本身可能会有明显的双星伴星印记。在这篇文章中，我们回顾了我们目前对黑洞二元性对潮汐扰动事件性质的影响的理解。我们讨论了超大质量黑洞双星的潮汐扰乱速率，第二个黑洞对碎片后退和吸积流形成的影响，以及超大质量黑洞双星探测潮汐破坏事件的前景。
Mergers are fundamental to the standard paradigm of galaxy evolution, and provide a natural formation mechanism for supermassive black hole binaries. The formation process of such a binary can have a direct impact on the rate at which stars are tidally disrupted by one or the other black hole, and the luminous signature of the tidal disruption itself can have distinct imprints of a binary companion. In this article we review our current understanding of the influence of black hole binarity on the properties of tidal disruption events. We discuss the rates of tidal disruption by supermassive black hole binaries, the impact of a second black hole on the fallback of debris and the formation of an accretion flow, and the prospects for detection of tidal disruption events by supermassive black hole binaries.
